Why shielded cable? It probably isn't really necessary in a home setup, you have some MRI equipment going off in the house?[/QUOT
If you are into SDR as a hobby you have no idea how bad RF pollution is. I see RF noise from 100 Hz to the 2 GHz band from multiple sources. Anything from a PC monitor going to sleep mode to modern digital utility electric meters generate noise, RGB bling included.
Not according to research. It is still beneficial to use a shielded but not grounded cable.The only thing with shielded is that the cable must be grounded at the switch end properly.
There's not much written on the subject, but I was able to find these:Interesting. Please provide data. I am curious as to how the cable shield would function without acting as a channel. EMI/RFI is not actually blocked by the thin foil shield...it is channeled down to ground.
True, but is there any evidence to the contrary or is the "common wisdom" just some default parroting that few tried to challenge is what interests me.Thanks for the links. I read both. The White Paper is the root of the Cabling Install article, which appears to be a DIRECT copy of the Siemon White Paper. The article did give credit to the Siemon paper, so no foul. I find the conclusions interesting, but without more to go on I have to stand by what I know right now which is that any shielded cable system should be properly grounded at the switch end. It is not that I am being stubborn, it is just one White Paper is not going to get it for me. I, for my job, have to follow and quote out ANSI/TIA specs, so that is drum I march to.
I set up a wireless bridge with Loco M5s (IIRC) on a UPS at least 4 years ago. The users don't contact me about updates very often, so I've seen over 400 days of uptime.It's been running for 1-2 years at this point with basically zero unnecessary reboots.
